- * How to enable Cache-As-RAM for the AMD Elan SC520:
- * 1. Turn off the CPU Cache (may not be strictly required)
- * 2. Set code execution PAR (usually the BOOTCS region) to be
- * non-cachable
- * 3. Create a Cachable PAR Region for an area of memory which is
- * a) NOT where the code is being executed
- * b) NOT SDRAM (Controller not initialised yet)
- * c) WILL response to read requests
- * The easiest way to do this is to create a second BOOTCS
- * PAR mappnig with an address != the PAR in step 2
- * 4. Issue a wbinvd to invalidate the CPU cache
- * 5. Turn on the CPU Cache
- * 6. Read 16kB from the cached PAR region setup in step 3
- * 7. Turn off the CPU Cache (but DO NOT issue a wbinvd)
- *
- * The following code uses PAR2 as the cached PAR (PAR0 and PAR1
- * are avoided as these are the only two PARs which can be used
- * as PCI BUS Memory regions which the board might require)
- *
- * The configuration of PAR2 must be set in the board configuration
